IMPRQVEMENT lhi WEATHER-STRIPS.

Specification forming part of Letters Patent No. 115,545, dated May 30, 1871.

' i LAMOS M. owns, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Weather-Strips, of which the following is a specification:

Nature and Object of the Invention.

Description of the Accompanying Drawing.

Figure 1 is a transverse sectional view of a door and sill with my improved weather-strip; Fig. 2, a sectional perspective view of the same; and Fig. 3, a sectional plan view.

General. Description.

A and A represent the opposite sides of a door-frame; B, a door hinged to the same at min the usual manner; and O, a raised and inclined sill or carpet-strip secured to the floor beneath the said door. The weather-strip is attached to the outside of the door, at the lower edge of the same, and consists of three main parts, namely, a fixed plate, D; a hinged plate, F, which forms the weather-strip proper; and a spring, G, arranged as hereafter described, to operate in conjunction with the door frame and sill to raise and release the said weather-strip. The plate D is secured at its upper edge to the door, and is inclined outward, as shown in Figs. 1 and 2, and the movable weather-strip F extends beneath the said plate D and is hinged to brackets 00 a, as best observed in Fig. 3. The hinge is so close to the rear edge of the strip that the latter, unless held up by the spring G, as hereafter described, will by its own weight fall to the inclined position shown in Fig.1, and rest upon the inclination a; of the sill G. The spring G is secured to the door beneath the plate 1), has a double inclined projection, b, arranged to act on the rear edge of the Weatherstrip F, and a tongue, I), Fig. 3, which, when the door is closed, bears against and is pushed back by a plate, (I, on the post A of the doorframe.

The operation of the above-described device is as follows: When the door is closed, as shown in Fig. 1, the spring G is held back of the Weatherstrip by reason of the pressure of its tongue I) against the plate d on the doortrance, so that the said weather-strip bears by. its own weight against the sill or carpet-strip G, and remains in close contact with the latter, even if the door is slightly moved, as when shaken by the wind, &c. When the door is opened in the direction of the arrow, Fig. 1, the spring G will be released, and will move slightly toward the weather-strip, and the latter, in being drawn over the upwardlyinclined surface a; of the sill, will be raised to the horizontal or nearly horizontal position shown in Fig. 2, its rear edge first striking the inclined portion y of the projection b of the spring, and then passing slightly beneath the latter until the inclined edge y of the spring bears upon the strip, as shown in Figs. 2 and 3. The spring, when thus acted on by the strip, will perform its duty of holding up the latter until the door is again closed, when the tongue b of the spring will strike and be pressed back by the plate on the door-frame, so as to release the weather-strip, the latter falling, as before, by its own weight, and not by the pressure of a spring, as in other an rangements of this class, until it rests upon the sill. v

In case the weather-strip should be accidentally depressed and released from the spring when the door is opened, it would, in closing the door, be raised so as to pass over the sill by the inclined surface at of the latter.

It is not absolutely necessary that the plate d should be secured to the postA of the doorframe, as it may be arranged on the post A, against which the door is closed; provided,. however, that the spring G be reversed.

Claim.

Ahinged weather-strip, arranged to beraised by an inclined door-sill, and to be caught and to this specification in the presence of two sill held in its raised position by a spring, G, when scribing Witnesses.

the door is opened, and to be released by the AMOS M. ULMER. said spring so as to again fall by its own Weight onto the sill, when the door is closed, all sub- Witnesses:

stantially as herein set forth. WM. A. STEEL,

In testimony whereof I have signed my name HARRY SMITH.
